H5N1 Avian Influenza Outbreak: Latest Developments and Key Diagnostic Tools

The recent outbreak of H5N1 avian influenza (bird flu) in dairy cows in the United States has sparked significant concern about the potential spread of this virus to humans. 

The Current Situation

In March 2024, two human cases of H5N1 infection have been confirmed, both linked to exposure to infected dairy cows. These instances mark the first documented cases of mammal-to-human transmission of this specific strain. Since 2022, the USDA has reported over 200 detections of HPAI A(H5N1) in mammals.

Background on H5N1 and Mammals

While it is uncommon, mammals can contract H5N1 through contact with infected birds, poultry, or contaminated environments. Direct transmission between mammals is considered rare but possible. Sporadic infections in mammals have been documented globally, including in Asia, North America, South America, and Europe. Recent cases have involved sea lions, foxes, and sea elephants.

Risk Assessment for Humans

The widespread presence of H5N1 in birds, poultry, and some mammals increases the potential for human exposure. However, the CDC currently considers the general public risk to be low. Individuals with occupational or recreational exposure to infected birds or animals, including dairy cows, are at higher risk.

Diagnostic Tools from Maxanim (Gentaur Group) Maxanim (Gentaur Group)

Early detection is crucial for containing the spread of H5N1. Maxanim offers a range of diagnostic tests, including:

  1. Avian Influenza Virus H5N1 RT-PCR: This rapid and accurate test detects the presence of H5N1 viral RNA in birds and potentially in mammals. (For more details, visit our website.)
  2. AffiVET® Bird Flu/Avian Influenza Virus (H5N1) Antibody ELISA Test Kit: This test detects antibodies against H5N1, indicating past or current infection in birds and some mammals. (For more details, visit our website.)
